Question

Use this function to predict the amount it will take in 2009 and in 2016 to equal the value of 1 currency unit in 1918

Answer 1

`V(19)\approx21.51,V(26)\approx24.47`

1) Since we have a Linear Function that models this situation, then we can plug it into that function.

2)

a)

Let's begin by predicting the value of that currency in 2009, i.e. 19 years since 1990:

`\begin{gathered} V(x)=0.4226x+13.4784 \\ V(19)=0.4226(19)+13.4784 \\ V(19)=21.5078\approx21.51 \end{gathered}`

b) Now, in 2016, i.e. 26 years since 1990:

`\begin{gathered} V(26)=0.4226(26)+13.4784 \\ V(26)=24.466\approx24.47 \end{gathered}`

Thus, in 2009 we would need $21.51, and in 2016, $24.47 to equate the value of 1 currency in 1918.
